A committee investigating Pakistan's under-performance at the World Cup has cited "poor leadership" from captain Inzamam-ul-Haq as a major factor.

"Inzamam's attitude was haughty and that of a dictator and more than one incident proved that," said committee chairman Ijaz Butt.

But he continued: "The poor performance reflects an overall failure of management at all levels."

Pakistan were eliminated at the first round stage after losing to Ireland.

Butt said the "entire cricket system" in the country needed to be "overhauled", adding: "No-one bothered to do the homework before the World Cup by sending someone to the Caribbean to get the knowhow about pitches and conditions and injuries to players were not treated seriously."

Inzamam resigned as captain following Pakistan's elimination and announce his retirement from one-day international cricket, but he hopes to continue his Test career.

The loss to Ireland was a major embarrassment for Pakistan

He has been replaced as skipper by all-rounder Shoaib Malik, who will lead the team in a best of three one-day series against Sri Lanka, which starts in Abu Dhabi on Friday.

Butt said the problems with Inzamam dated back to last September when Pakistan forfeited a Test match in England after the team were accused of ball-tampering by the umpires and continued during a subsequent series in South Africa.

"Inzamam became an autocratic and introverted captain after the Oval fiasco last year and his refusal to go on the field was overlooked by then PCB [Pakistan Cricket Board] chairman Shaharyar Khan," said Butt.

"When the Board sent a selector with the team on tour to South Africa in January-February this year, Inzamam did not involve the selector in team selection."

The committee also looked at claims about possible match-fixing by members of the team during the World Cup in the Caribbean.

But they found no evidence to support the allegation, which was strenuously denied by Inzamam when he returned home from the Caribbean in March.

"We heard several allegations but they were nothing more than that. We found nothing to suggest the team had fixed any games," Butt added.

"We invited Shaharyar Khan to corroborate what he said in the press about targeted fixing, but he didn't come."

The commitee has recommended that a seniority system for paying players should be abolished, with only the captain and vice-captain receiving more than the basic rate.
